Hi David & Ann,
It is no problem at all to get detailed maps showing even the smallest villages in Spain, France & Italy as I have them all.
I would very strongly recommend that you buy them locally in each particular country as much better than maps that you will buy here.
Town and village names will be spelt the same way as you will see them on sign posts.
Where to buy you may ask? At most garage forecourts!!
The Spanish one will also cover Portugal.
Cepsa, Campsa and Almax are all good editions for Spain/Portugal, mine cost me about £15 in 1992
Michelin are good for France but you will need the large scale edition with every village and bridge heights on. ( Atlas Routier) 3 mile to 1 inch, cost me 110ff in 1992
My Italian map is tucked away but no problem to get hold of one.
